Well, yes, in theory. If you can tell a _working_ synthetic route for
this one directly from the formula or name, I am truly impressed!

Somehow, I am not surprised :-). It took me about three months to
get that molecule synthetized, since I first heard its structure.

Vdet is approximately 10000 m/s as pure substance, about 9500 m/s as a
plastic bonded composition. Density is about 2,1 g/cm3. Stability is
about equal to that of octogen, which is better than TNT. Of course,
that only applies, if you have the right polymorphic form - there are
at least 8 different forms and each has different sensitivity, density,
performance etc.

I think the HNIW is just an extension to the family of polynitramines -
it is a homologue to hexogen and octogen. The next generation
explosives are compounds such as N4 and N8. So far, nobody knows a
synthetic route for them, though. The closest ones to them is probably
ammonium dinitramide (NH4N(NO2)2) and ammonium azide.
